摘要
应用CAD软件CATIA对不同网格尺寸下矩形截面悬臂梁的最大应力进行有限元分析,并与理论计算值进行对比,得出网格尺寸与有限元分析精度的关系,并给出推荐的网格尺寸及误差补偿建议。
The CAD software CATIA is used to analyze the maximum stress of rectangular cross-section cantilever beam under different mesh sizes,and the results are compared with the theoretical values.The relationship between the mesh size and the accuracy of finite element analysis is obtained,and the recommended mesh size and error compensation suggestions are given.
